EQWBITING MACHINE.

Specification of Letters Patent.

Patented Apr. 16, 1918..

Application filed July 19, 1917. Serial no. romeo.

. To all whom it may concern: Y

Be it known that I, Janus E. SIMrsoN, a citizen of the United States,and resident of borough of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a ecification;

This invention relates to typewriting mechines, and it'oomprises certainnovel means,

based upon my application Serial No. 172926, filed June 5, 1917, wherebyan infing ribbon may be supplied with ink during the operation of themachine.

My present improvement complrehends the employment of a revoluble in ingroller, mounted in a fixed position near the ribbon; which latter isintermittently moved into and out of contact with said roiler by aslidable member, that is normally spring held in retracted position. Theslidable member is actuated from a moving part of the machine throughnterconnecting means; and means,

operating in conjunction with said sliding member, serve to rotate saidinking roller.

Other feature and advantages of my said invention will hereinafterappear.

in the drawing:- Figure 1 is a plan view showing portions of atypewriting machine, including my inn-- provement. a

Fig. 2 is a vertical view of the ink roller and ribbon actuatingmechanism.

Fig. 3 is a. vertical rear view showing the connection betweeutheeseapement mechanism and slidable member, toectuate the latter, and v iFig. 1 is}. plan view of Fig. 2. As on exempts. of a method of carryingout my invention 1 have shown. it uppiied to an Underwood typewritingmachine, wherein 1 indicates the machine frame; 2 the U- shaped framefor the type hers, 3 the key levers having keys 4, 5 the platen, and 5the escapement rock shaft carrying yoke 7.

The inking ribbon 8 is shown as extending between the spools 9 and heldat the printing point by guide 10.

A. mount 11 is securedas by a screw 12 upon frame 2, said mountextending forwardly, beneath the ribbon, and having revolubly securedthereon a pad or roller 13, whose peripheral surface lies in opposed,non-contactmg relation to the outer surface of ribicon 8. A. slide 14,having slots 15, is imposed upon mount 11, which has studs it on gagingsaid slots, whereby the movement of the slide may be limited and guided.Tensional means, as a spring 17, engaging the mount 11 and slide 14,serves to hold said slide normally retracted, so that the ribbon, whichfeeds through a guide frame 18 carried by slide 14, is thereby held outof contact with roller 13.

The ribbon is moved against the roller '13 to receive ink by means whichcause the shifting of slide 14 against the tension of spring 17, andwhich may communicate the motion of the escapementinechanism to saidslide. In the "example illustrated I have attached a bracket 19 to theyoke 7 ,a rod 20 extending forwardly from said bracket, and engaging, atits forward end, as with an arm 20" depending from slide 14, said armbeing pivoted, as at 21, to a bracket 22 carried'by the mount 11. Bythese means the slide 14' is impelled forwardly, to bring the of thefinger keys.

The roller 13 may be provided with a wheel or disk 23 having peripheralteeth 24, for engagement by a pawl 25 carried by slide 14; whereby, inthe forward movements of said slide the-roller 13 has partialrevolutions imparted thereto, so that the said roller is positivelyturned and caused to present successive portions of peripheral inkingsurface to' the advancing ribbon. A spring finger 26, carried by themount 11, may beer against the teeth 24 to limit the turning motion ofroller 13;

A coiled spring 27 may be secured to and interposed between the bracket19 end a. nut

$8 at the rear end of rod 20, said spring comprising a cushion whichwill absorb the shocks that would otherwise be transmitted to the slide14: in its intermittent impulses.

Fluid ink may be supplied to the roller 13, which is composed ofabsorbent material, as by a cup or reservoir 29, mounted on the uppersurface of he roller, and having means of communication with saidroller. Variations may be resorted to within the s irit and scope of myinvention, and parts t erect used without others.

I claim:--

1. In a typewriting machine having a. ribbon oveble across the printmgpoint,

the combination of a revoluble inking paoi,

tently move said ribbon into contact with a said pad.

3. In a typewriting machine having finger keys, and a ribbon movableacross the printing point, the combination of a revoluble inking pad, afixed. support therefor, sliciable means engaging said ribbon to hoidthe latter normally out of contact with said pacl, and means, actuatedby sai& finger keys, to intermittently sbiit saiol slidable means andthereby carry said ribbon into contact with saicipad,

4:. in a typewriting machine having finger keys, and a ribbon movableacross the rinting point, the combination of a revoluble inking pad, afixed support therefor, siiclable engaging means for said ribbon, aspring to hold said slidable means normally retracted with said ribbonin noncontact ing relation with sairi pad, anti means, ac

messes mated by said finger keys, to intermittently shift saici slidablemeans and thereby carry said ribbon into contact with said pad.

5. In a typewriting machine having finger keys, and a ribbon movableacross the printing point, the combination of a revolw ble inking pad, afixed support therefor, a ribbon engaging slide upon said support, guidemeans therefor, and means, actuated by said finger keys, tointermittently shift said sliclable means anii'thereby carry said ribboninto contact with said pad.

6. In a type-writing machine having finger keys, and a ribbon movableacross the printing point, the combination of a revoluble inking pad, afixed. support tiierefor, sliclable means engaging said ribbon to holdthe latter normally out or" contact with sai i pad, means, actuated bysaid finger keys, to intermittently shift said slidable means andthereby carry said ribbon into contact with said pad, and means,carrieol by said slidable means, to intermit tently revolve said pad.

Signed at borough oi Brooklyn in the county of Kings and State of NewYork this 17th day of July, A. D. 1917.
